Manchester United will suffer a third successive home defeat in the Premier League when they host West Ham this weekend, according to British prime minister David Cameron.
The champions have not recorded a league victory at home since the narrow defeat of leaders Arsenal in early November, with both Everton and Newcastle having triumphed in the two games at Old Trafford since.
Manchester United are, however, on the back of three consecutive wins in all competitions without conceding a goal but Cameron expects David Moyes' side to slip up once again when West Ham visit on Saturday.
The premier was taking part in the BBC Sport predictions for the round of weekend matches, pitting his wits against pundit Mark Lawrenson, and has backed the Hammers to record a 2-1 win against Manchester United, despite having notched only three league successes this season.
Sam Allardyce's side do, however, travel to Manchester having claimed a morale boosting Capital One Cup quarter-final victory away to rivals Tottenham in mid-week, and arrive at Old Trafford knowing three other teams have won there this season.
West Ham are perilously close to the drop zone at present and three points could carry them as high as 15th, while Manchester United can propel themselves into the Premier League's top six if they can arrest their poor home form.
